Abstract
AbstractA novel filler surface treatment is employed to produce thermally conductive composites using an aramid nanofiber (ANF) and pentaerythritol (PER) grafted onto the surface of graphite nanoplates (GnP). The resulting composite exhibits exceptional properties, including a high through‐plane thermal conductivity of 4 W mK−1, a high tensile strength of 163.58 MPa, and an improved flame retardancy. When the composite is applicated in central processing unit (CPU), the efficient thermal management performance is achieved with a decreased operating temperature of 12 °C. The ANF/GnP–PERANF composites are promising for enhancing thermal management in electric devices. The manufactured ANF composites will open new avenues for advancing the development of next‐generation thermal management systems.
